Specification of Letters Patent.

Patented June 20, 1911.

To all whom it may concern:

Be it known that I, FELIX J. SMITH, a citizen of the United States ofAmerica, residing at Lindsey, in the county of Sandusky and State ofOhio, have invented new and useful Improvements in Mixing-Machines, ofwhich the following is a specification.

This invention relates to devices for mixing mortar, cement, concreteand other plastic compounds of a like nature.

The invention has for its object to produce a readily portable device ofsimple and inexpensive construction which may be efficiently utilizedfor the purpose of mixing various plastic compounds.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaim may be resorted to when desired.

In the drawings,-Figure 1 is a side elevation, partly in section of adevice constructed in accordance with the invention. Fig. 2 is a topplan view of the same. Fig. 3 is a sectional detail view, enlarged,taken on the line 33 in Fig. 2.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The circular or cylindrical mixing pan 1 of the improved device isfixedly mounted upon a platform 2 which in turn is suitably supportedupon a running gear including transporting wheels 3, 3. Formed orsecured upon the mixing pan 1 adjacent to the upper edge of the latteris an exteriorly disposed rack flange 41.

A vertical shaft 5, which is supported for rotation centrally in themixing pan, carries at its lower end a bevel pinion 6 meshing with abevel pinion 7 upon one end of a main driving shaft 8 which is supportedfor rotation in brackets or bearings 9 upon the underside of theplatform 2. The driving shaft 8 carries adjacent to its outer end apulley 10 adapted to be belted to a suitable motor or to a source ofpower of any description,

Suitably mounted upon and loosely engaging the upper end of the shaft 5is an arm or bar 11 provided with hearings on its upper face for ahorizontal shaft 12 which is connected at one end by miter gearing 18with the shaft 5. The opposite end of the shaft 12 is connected by mitergearing 14 with the upper end of a vertically disposed shaft 15 which issupported for rotation in the outer end of the arm 11, said shaft 14being provided adjacent to its lower end with a gear wheel 16 meshingwith the rack flange 4 upon the pan or receptacle 1, said gear wheel 16being provided with a. flange 17 that catches beneath the rack flange 4,thereby preventing upward displacement of the gear wheel 16 and theparts associated therewith. The arm 11 carries an anti-friction roller18 riding upon the upper edge of the pan 1.

'A second radial arm 19, similar to the arm 11, is provided, said armextending from the shaft 5 to the rim or edge of the pan 1, beingequipped with an antifriction roller 18 riding upon the upper edge ofsaid pan 1. The arm 19 may be connected with the arm 11 by a brace 20 toinsure strength and stability of the device. The arms 11 and 19 are eachprovided with clips or clamps 21 and 21 for the passage of the handles22 and 22 of suitably constructed shovels or scrapers 23 and 23 whichare substantially alike, except that the shovels connected with the twoarms 11 and 19 are adapted to move the material engaged therebyrelatively in opposite directions, that is to say, toward and away fromthe rim of the pan or receptacle 1. The arm 19 is also provided with ahingedly supported scraper 24 and with uprights 25 supporting a rockshaft 26 having radially extending arms 27 which are connected with thescraper by means of links 28. The rock shaft 26 also has a lever 29 bymeans of which the scraper may be raised to a nonengaging position orlowered to a position in which it will actively engage the bottom of thepan for the purpose of conveying the material contained therein in thedirection of a discharge aperture 30 in the bottom of the pan for whicha suitable slide or closure 31 is provided.

As will be readily seen from the foregoing description, taken inconnection with the drawings hereto annexed, when power is applied tothe shaft 8, motion will be transmitted through the shafts 5 and 11 tothe vertical shaft 15 carrying the gear wheel 16 which meshes with therack flange at the upper edge of the pan. direct pull will thus beexerted upon the outer end of the arm or bar 11 and from theretransmitted through the brace 20 to the arm or bar 19, said arms or barscarrying the shovels whereby the contents of the pan will be th'oroughly a gitated and mixed. When the contents of the pan has beensufliciently treated, the scraper 24 may be lowered to a positionengaging the bottom of the pan, the 'col'it'e'nts of which may thus beconveyed to the discharge opening.

This device is extremely simple in construction, and it has been foundvery efiicient in operation. One advantageous feature of the device isthat when other power is not available it may be readily worked by handor animal power which may be applied directly to the outer extremitiesof the arms or bars 11 and 19.

Having thus described the invention what is claimed as new, is

In a mixing machine; a fixed circular pan, an axial shaft supported forrotation in said pan, a radial arm supported upon said shaft forrotation about the latter, said arm being extended beyond the peripheryof said pan, means carried by said arm actuated by said shaft andengaging the periphery of said pan to cause the rotation of said armabout said shaft-,mixing elements carried by said radial arm, and meansfor transmitting motion to said axial shaft In testimony whereof I aflixmy signature in presence of two witnesses,
